Forcing a custom indicator to show the "on" skin?

Basically a small time saving exercise - is there some easy way to force a custom indicator to show the "on" skin of a skin using variables? I've tried forcing variables to "true", "on", 1 etc. but I can't seem to get the indicator to change as a result of them.

"SETIND" - This lets you set the sate od custom indicators from SDK or skin. The Indicator's code needs to start
with an exclamation mark (!), as in: Ixx,xxx,....,"!MYINDICATOR" -- Indicators are OFF by default.
Examples: "SETIND;!MYINDICATOR;ON" or "SETIND;!MYINDICATOR;OFF"

Well the main goal was to avoid making a whole lot of individual images to set as indicators, but my current work around is just going to be putting a whole lot of indicators on separate skins to on in my ExecTBL I was just wondering if there was something obvious I was overlooking to do this.

Currently I have a row of buttons which I want to highlight when specific skin subfeatures are activated. RR doesn't support subskins and the like however, so I need a different one on each skin to be lit up. Easiest way to do this is to put an indicator over the buttons that's always on when the different skins load up.
